Given numbers are 680, 145, 893, 378

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 145 are 5 x 29

Prime factors of 893 are 19 x 47

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 680, 145, 893, 378

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(680, 145) = 19720

GCD(680, 145) = ( 680 x 145 ) / 19720

= 680 / 145

= 680

Step2:

LCM(5, 893) = 4465

GCD(5, 893) = ( 5 x 893 ) / 4465

= 5 / 893

= 5

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 680, 145, 893, 378 is 1
